2. The discrete input configuration shown in Figure 32-42 will result in a yellow "PITOT TEMP"
alert that will appear on the PFD any time the GAP 26 heater is powered off, or if it is powered on
but the probe temperature is below approximately 25° C (77° F). If pitot heat is powered and the
probe temperature is sufficiently high, the yellow "PITOT TEMP" alert will not appear.
3. The discrete input configuration shown in Figure 32-43 will result in a yellow "PITOT TEMP"
alert that will appear on the PFD similar to Configuration #2, with additional logic that
automatically prevents the yellow "PITOT TEMP" alert from appearing if the outside air
temperature is above approximately 7° C (45° F). This configuration provides the same indication
as Configuration #2, but hides the pitot temperature alert when flying in warmer weather
conditions.
Lean Assist
Lean Assist is a feature that monitors and detects peak temperatures for EGT or TIT as the pilot leans the
engine's air/fuel mixture. When configuring EGT or TIT inputs, Lean Assist can be enabled or disabled. If
Lean Assist is enabled, the LEAN softkey will appear on the ENG page in normal mode. Lean Assist
should be disabled for engines that do not have pilot-controllable air/fuel mixture.
